OOH marketing can be done through four main mediums, namely- billboards, street furniture, transits and alternatives.
Billboards – One of the most traditional forms of OOH advertising has been billboards. They are still in vogue and have moved a notch higher technically with the incorporation of digital billboards.
Street Furniture – Advertising through street furniture like telephone booths, bus shelters and news racks is very rampant in urban locations.
Transit – Placing an advert on things that can move and constitute transit advertising, such as buses, metro, trains, taxis and trucks. Electronic and static advertising at airports, platforms and bus stations also fall under this category.
Alternatives – Alternatives include aerial, brochure, postcard and cup advertising which are more creative and targeted.
